Be itfknow-n` that I, Anescertain new andquseful Improvements in 111+ .ternal- Combustion Engines, of-Vwhieh the .following is a full, clear,and exactzdescrip-V tion. Y

The invention relates; to internal.combos` tionengines.-

One-objectf'of the inventionis to. provide an internal combustion engine comprising a rotary l valve -lwhiclifhas :a i chamber -therein for the circulation .of `cooling Water, with.

means for preventing the leakage vof: Water' 4 from the valve at the. inlet and .outletvconnections therefor.

A further object. ofthe vinvention is to -provide water-tight `connections which are'vdisposed in-'the engine casing.Y

A' still urtherobjeet othe-invention-,is-

A- furtherobject of the inventionv is. to-

provide means for preventing the escape offiuid from. the engine cylinder between the working-- faces ofA the'rotary' valve and-its seat.

Lastly; the invention designsto improve theconstruction and operation'of rotaryvalve mechanism forinternal combustion engines.

The invention-consists in. the several novel features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

Fig.. 11 t11s a. detail of the retaining ringfforthe'- stu 'Ehe engine comprises a suitable casting Afin which the cylinders a, iti-any desired number,l usually four, are-formed. Pistonsb are slidably fitted in the cylinders lin the usualmanner, to drive aY crank-shaft"4 (not shown), aswell understood in the-art.- A cylindrical valve-seat d isformed-ina Wall; a4 of` case A` and' extends longitudinally across the top of .all the cylinders. A'cylin. drical rotary-valve e is-itted'in'the' seat d@ The casting A servesA as an'enginecasing and'comprises anouter. vvallorshell a" which provides a water-ijacket around'tle cylinders, a chamber azf'being'formed 'be' tW-een the cylinderwalls and vthe'outer wall, for` the circulation of cooling-water. An inlet connection fis formed in one side of wall affor -apipe which conducts cold Water to the Water-chamber in the casing, this pipe being'usually connected? to a-fcirculat ingA pump which receivesWater from the cooler 'or radiator, (not shown), as usual'inthe-art. The top 'of onelend ofthe-enginecasing A is-provided withv an outletJ to which a discharge-pipe fzfis connecte forconductingthe'cooling water,- after it has cooled thec'ylindersl and the valve, to the radiator.l Y

The outer walls of casing' A are formed to,leave a water-chamber a? aroundwall a4 in which/the valveeseat d is formed,'andfthis chamberv communicates with-the chambers a2 around'l the cylinders. Resultantly, water surrounding walls of all the cylinders andv the valve-seat.

The rotary valve is formed with relatively A offset through-ports e" (one for each cylinder) to successively serve as exhaust and intake ports. At one side of'the top of casing lA, an inlet port g is formedvfor each cylinder and at lits opposite side an-exhaustport g is formed for each cylinder. An opening-g2 is formed'between the valve-seat and 'peach of the cylinders, respectively.

A suitable manifold (not shown) vsupplies combustible fluid to all of the `inlet ports and an exhaust manifold (not shown) carries oli -the products ofcombustion escaping through allv of tlfie-p'ortsvg,v as Well understood in the art. The'operation of each off' foroedinto these chambers will'cool these "be the-same,

' rotated cylinder.

which IL or inv one end of chamber a.

which receives the. valve-"ports for the several cylinders will except that they will operate in s operly timed Succession to cause the pisto to be operated successively, as well und stood in the art.

In o e'ration,.valve e will be continuously 'the proper ratio, (usually l to 4) to the. en

orrst cycle, a charge of combustible mix ure will be drawn through inlet g, valve-port and opening g2, and into the -During the compression-stroke and the power-stroke, the valve-'port will remain closed and during the fourth cycle, said port will be disposed to `permit the products of combustion toescape through .the exhaust port g Water entering the bottom of the water-jacket at inlet f will circulate around thel ylinder-walls and also aroundthe valve-casing or wall a* in transit to the outer'pipef'. Valve e extends from end to end 'ofthe body-'sectionof valve-casV ing-a4 and projects beyo d the ends thereof. The rotary-valve is..hol w or tubular to' provide a passage or chamber e4v extending from end to endthereof, so AWater will flow longitudinally through the valve. The

rear end of. valve e terminates ina head 7:, is fitted and secured to the casing A, by bolts t;vv This head is provided with a chamber or duct Il? Water from the Water-chamber a2 varound the cylinders, through Aa pbrt I1.a in the end of casing A and'an inlet p'ort h* in the head. A cap .i is 4removably secured to the head by bolts 1I .to afford access to the outer end of the valve e. The chamber k2. serves to conduct Water into one end of valve e adjacent said chamber, the end of the valve being open to direct water Afrom-chamber it into the .Water-chamber e* in the rotary-valve. A small by-pass duct la.

isformed in the head l1, and conducts Water `from the top of chamber h2 to one end of the water-chamber a3 to of air or steam pockets in the valve, the head The front end of valve e is alsofopen and is disposed in ra valve-head is which is secured with a ring k', to the front end of casing A. The outer end of head k is provided with a removable cap k2 to afford access to the valve when desired. A Water-chamber 7c? is formed in head to conduct water flowing out of the rotary-valve to a duct .f3 in the head c, which conducts the water to outlet-pipe f2. As a result of this construction, cold water passl ing to the water-jacket through vinlet f will initially circulate around the engine-cylinders I) Where itstemperature 'will be raised. A portion of this water will flow around the Wall a in which the valve-seat for thel rotary-valve e is formed, to cool said Wall, and after that the Water will ow to the outlet f. Another portion of the water will y e-shaft, so that duringthe initial' downestro prevent the .formation pass through opening z at the rear of the casing to the water-chamber in head h, thence into one end of the rotary-valve e and thence through the chamber in said valve vto cool the cylindrical Wall of vthe valve and the Walls around the ports e which control the passage of fluid' to and from the enginecylinders. This water, after passingthrough the rotary-valve, passes through chamber k. and duct fil in head c to the water-outlet f3.

around the engine-cylinders is divided into two streams, one of which fiows through and cools the rotary-valve and the other ofwhich flows around and cools the Wall of the valve- .Resultantly, the cooling water, after passi seat. This manner of circulating the cooling liquid causes effective equalization of the temperature of all portions of the rotaryby variations in because the variations will effectively i valve-seat, because there is escape for the. liquid from the highest portion of the Waterchamber in the head to the adjacent end 0f chamber a3. A sprocket-Wheel Z is provided on an exposed portion of the rotary-valve, and this sprocket wheel may be driven by any. suitable mechanism from the crank# shaft.

Lubricant is supplied to the periphery of the rotary-valve e and to thel valve-seat d through one the casing, from any suitable source of supply. In practice, l the escape of lubricant to the water-chamber and'also to exclude water from the Working surfaces of the valve and its seat. purpose, a packing p is provided around each end of the rotary-valve in the heads in which its ends terminate. It is desirable to adjust this packing without opening the the Water-chamber which would make it necessary to drain the engine before the packing could be adjusted and to this end devices are provided for adjusting the packings from Ythe outside of the casing. A follower-ring p is provided for each-packing p. Each head, is provided with oppositely disposed pairs of lugs p2. An adjusting-'stud ory or more ducts o at one side of disposed arms g which.
